Hello all. My ADSLRouter currently runs ver.1.02.1 firmware, has operated ok - bar just one lockup during last 12 months (and not sure that wasn't just BT or the IPS's fault). There is some muttering from teenagers about sleepy WiFi performance occasionally so thought it kind to ask if ver.1.03.0b4 upgrade would help on 802.11b throughput? Previous posts & feedback comments don't suggest on balance if it's a great improvement. Would appreciate opinion before crawling into loft space towards the reset button (-: Thanks. BTW ... haven't found heat a problem in the summer & no danger of overheating today, must be just above freezing in the roofspace!
